August 16, 2012--Invasive species from Japan ride tsunami debris to American shores (Los Angeles Times)

Millions of hitchhikers are being carried to American coasts on large pieces of debris set adrift by last year’s Japanese tsunami. Now scientists are concerned that these invading organisms — both plants and animals — could disrupt marine ecosystems in their new homes.


June 3, 2011--River mystery solved: Scientists discover how 'didymo' algae bloom in pristine waters with few nutrients (Science Daily)

The pristine state of unpolluted waterways may be their downfall, according to research results published in the journal Geophysical Research Letters.


July 11, 2010--Scientists roll out mats to kill Lake Tahoe clams (Denver Post)

Scuba-diving scientists are unrolling long rubber mats across the bottom of Lake Tahoe coves in an attempt to quell a clam invasion that could cloud the world-reknown cobalt waters. The half-acre mats are designed to smother dime-sized nonnative Asian clams that can reach populations of 5,000 per square yard.


April 7, 2010--Study says U.S. waterways are warming (New York Times)

Many streams and rivers in the United States are getting warmer, with the greatest increases in urbanized areas, according to research to be published in an upcoming edition of the journal Frontiers of the Ecology and the Environment.


January 9, 2010--NASA study: Lake Tahoe water temps warmer (Denver Post)

A recent NASA study showed Lake Tahoe's water is warming twice as quickly as regional air temperature, lending weight to predictions of warming lake temperatures made by UC Davis researchers in 2008.


November 6, 2009--Study: Nitrogen pollution worsens in Rockies lakes (Denver Post)

Airborne nitrogen pollution from vehicle exhaust and farm fertilizer is turning algae in the alpine lakes of Rocky Mountain National Park into junk food for fish, a study says. A similar phenomenon is occurring in Sweden and Norway, according to the study of about 90 high-elevation lakes set to be published in the journal Science on Friday.


March 8, 2009--Cherry Creek under scrutiny (Denver Post)

Angling and conservation groups have sounded an alarm concerning a 10 a.m. Tuesday meeting of the Cherry Creek Basin Water Quality Authority, fearing an attempt by pro-development board members to relax standards on Cherry Creek Reservoir. The groups are troubled by an algae overload from excess nutrients released into a 400-square-mile basin contained by the impoundment.

August 12, 2008--'Blitz' to test water at hundreds of locations in Rocky Mountain National Park (Rocky Mountain News)

The idea is to circumvent the kind of problem researchers face when they test one stream on a sunny day, another the next day after a rain, a third the following day when the algae are photosynthesizing to beat the band.
